本研究はインドの鉄筋コンクリート造住宅におけるエンボディドカーボン(EC)を評価し、容積率(FAR)と地震帯が材料強度と排出に与える影響を分析。FAR上昇により材料需要が増加し、鋼材がECに強い線形相関を示す一方、コンクリートは非線形傾向を示した。地震帯による鋼材需要の増加も確認され、低炭素設計の重要性を提言。
English
This study quantifies embodied carbon (EC) in reinforced cement concrete residential buildings in India, analyzing how floor area ratio (FAR) and seismic zones affect material intensity and emissions. Results show steel has a deterministic linear correlation with EC, while concrete shows nonlinear trends. Seismic variations increase steel and concrete demand by 21-31% and 22-30% respectively, highlighting the need for material-efficient design and low-carbon alternatives.

📄 Abstract（原文）
Abstract India’s residential construction sector is a major emitter of greenhouse gases, with embodied carbon (EC) increasingly critical as operational emissions decline. This study quantifies EC in reinforced cement concrete (RCC) residential buildings in Ahmedabad, focusing on how floor area ratio (FAR) and seismic zones affect material intensity and emissions. Using a Life Cycle Assessment (LCA) framework aligned with EN 15978 and ISO 14040/44, baseline EC values were derived and material–emission correlations analyzed. Results show that increasing FAR from 1 to 5.5 raises the built-up-to-carpet area ratio by 22%, driving sharp material demand. Steel demonstrates a deterministic linear correlation with EC (R 2 ≈ 1.0), while concrete follows a non-linear trend (R 2 = 0.7–0.9), stabilizing beyond FAR 3. Seismic variations elevate steel demand by 21–31% and concrete demand by 22–30%, underscoring reinforcement needs in high-risk zones. Regression models confirm strong predictive power (R 2 = 0.97 for steel, 0.92 for concrete). The findings highlight steel’s dominant role in structural emissions and underline the need for material-efficient design, stricter codes, and low-carbon alternatives. By linking EC to FAR and seismic conditions, the study provides quantitative evidence to build more evidence and guide India’s low-carbon building policies and pathways.
